Another sign that the iPod is going wireless?

Read into this what you will (and we're so tempted to refrain from our usual banter on this one), but a job posting has shown up on Apple's website looking for a hardware engineer to work in their iPod division who has experience in a variety of wireless protocols, including "GSM, Bluetooth, [and] IEEE 802.11". Some sort of wireless iPod in the works? Maybe, maybe not, but there has been plenty of speculation about this, and it sounds like they're at least might be exploring their options.
